LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 482,346, dated September 13, 1892.

Application filed January 21, 1892. Serial No. 418,771. (No model.)

To all whom it may concern.-

Be it known that I, MAHLON H. FINE, a citizen of the United States, residing at Alden Station, in the county of Luzerne and State of Pennsylvania, have invented a new and useful Lubricator, ofwhich the following is a specification. Y l

This invention relates to oil-cups; and it has for its object to provide an oil-cup or revolving lubricator that is designed to be secured to the sleeve or drum of any frictiongearing and which will deposit the lubricant upon the shaft over which the sleeve or drum revolves at every revolution of said sleeve and which will only feed at such intervals wh en in motion and while stationary will not feed. It is thus the primary object of this invention to provide an oil-cup which materially saves oil and prevents the friction devices from becoming greasy and out of order, while at the same time sufficient lubricant is fedto the shaft to prevent the sleeve from cutting.

With these and many other objects in view, which will readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination, and arrangement of parts hereinafter more fully described, illustrated, and claimed.

In the accompanying drawings, Figure 1 is a front elevation of a friction-controlled sleeve or drum provided with oil-cups constructed and arranged in accordance with my invention. Fig. 2 is a transverse sectional view through one of the oil-cups and the Sleeve with which the same is connected. Fig. 3 is a detail in plan of the buffer or cushion-cap.

Fig. 4 is a detail in perspective of the buerplate.

Referring to the accompanying drawings, A represents a shaft which accommodates the long sleeve or drum B, working over said shaft, which is supported in suitable bearings at each end, according to its location. Keyed upon each end of the revolving sleeve or drum B are the spiders or wheels C, which are adapted to control the movement of said sleeve or drum. This gearing is a portion of the friction-gearing used for hoisting purposes, and is sucient to show the adaptation of my improved oil-cups thereto. Motion is imparted to the shaft A by suitable gearing and by means of suitable friction clutches or devices thrown into engagement with the said spiders. The said drum or sleeve B may be thus revolved with the shaft to hoist, while, on the other hand, when the friction devices are thrown out of contact wit-h said spiders the said drum will revolve loosely upon the shaft and lower the object hoisted. Thiswill be quite apparent. The said sleeve or drum B is provided with the upwardly extending threaded nipples D, which receive the threaded lower end of t-he spout E of the funnel-shaped oil-cup or revolving lubricator F. The bore of the spout E is slightly greater than the bore of the nipples opening onto the axle, the purpose of which being readily apparent. The said oilcup F is provided with an upper exteriorlythreaded neck G, which receives the detachable cover I-I, engaging said neck and provided upon the under face with a clampingplate I, having a series of clamping-arms J, that are adapted to receive and removably clamp in position the rubber cushion or buffer K. A feeding-plunger L works within said funnel-shaped oil-cup and through the spout E thereof and into the nipples in the revolving sleeve or drum, and as the said sleeve revolves and carries the oil-cups therewith it can be readily seen that the said feeding-plunger will alternately be thrown back against the cushion upon the inclosing cap to allow the oil to flow from the spout into the nipples and into said nipples D'in the sleeve or drum to carry the portion of the lubricant worked therein to the shaft against which the plunger will strike. A continuous lubrication of the shaft and sleeve is thus obtained as long as the said sleeve is in motion; but the lubrication ceases when the revolutions of the sleeve cease. It is not designed to fill the oil-cup with running oil, but with alubricating-grease which will not freely run whenever the oil-cup may be in a vertical position but portions of which/can only be carried to the shaft by the working feeding-plunger. The cushion not only prevents a wearing upon the inclosing cap and cushions the shock of the feeding-plunger Athereon, but also serves as a springv to assist in throwing the plunger into the spout and nipple, and said cushion may be easily and readily replaced when damaged or worn out, as

will be readily seen. It may be further observed at this point that the plunger L tits or Works Within the spout E only sufficiently tight so as to guide the same, in order that the lubricant may work into the reduced nipple when the plunger has been thrown back against the cushion, and, on the other hand, when the lubricator has assumed a vertical position to allow the plunger to bevthrown into the nipple the said plunger ts the nipple tightly, so as to form a valve which prevents the oil working down into the nipple without the use of valves.

The construction, adaptation, and uses of the herein-described oil-cup are thought to be apparent without further description.

It may be additionally noted that this revolving lubricator is also especially adapted to be used at the head of slopes or shafts of mines particularly or in any location on machinery where it is necessary to use asliding sheave for hoisting purposes. By drilling a hole through the hub of the sheave the lubricater is readily attached, and thus insures a perfect lubrication of the shafting and also of the sheave. At the same time the revolving lubrioator materially saves the oil, as already stated, inasmuch as the same does not feed unless the sheave, sleeve, or other por tion of machinery to which it is attached is in motion. Much oil is lost by the ordinary lubricating devices used in connection with slidingysheaves `by throwing the loose oil on the shafting, which in every case is scraped oft the rst time the sheave slides across the shaft.

Having thus described my invention, what Iclaim, and desire to secure by Letters Patent, is-

The combination, with a shaft and a sleeve' or ydrum Working thereover and having a threaded nipple, of a funnel-shaped oil-cup or revolving'lnbricator carried by said sleeve or drum and provided with a threaded spout secured within said nipple and of a less di- -anneter than the same and an inclosing cap or cover provided with a clampingplate having a series of clamping-jaws, a butter and spring-imparting cushion removably secured between said clamping-jaws, and a feeding plunger-rod, ot the same diameter throughout, working in said oil-cup and spout and adapt? ed by the revolutions of said sleeve to be thrown alternately against said cushion and ,the shaft, substantially as set forth.

In testimony that I claim the foregoing as my own 1 have hereto axed my signature in the presence of two witnesses.
